I'm a full-stack engineer at Vitraga Solutions, building production systems for a 260-year-old Indian travel brand and for an Australian NDIS provider. I went from intern to engineer doing it.

My work leans into the hard parts: LLM features in real products, payment gateways, multi-tenant SaaS, and CRM pipelines that move 5,000+ leads. On the side I ship developer tooling used by 450+ people.

ReThink

Digital-wellbeing app — Android

A screen-time app that actually intervenes. I wrote a custom Kotlin AccessibilityService and a from-scratch React Native native-module bridge to detect the foreground app in real time and hard-block distracting apps instantly — even when the app is force-closed (HeadlessJS). Adds AI coaching (Gemini + LangChain), scheduled Focus Mode, and 15-minute background sync.

AI trip-planner — B2C + B2B

The consumer site and franchise-agent portal for a 260-year-old Indian travel brand. I built an AI trip-planner (LangChain + GPT-4o + pgvector semantic search) that cut agent package discovery from ~20 min to under 2, with in-chat OTP lead capture and two-way TeleCRM sync powering 5,000+ leads — plus a unified HDFC / ICICI payment layer.

Client · via Vitraga Solutions
